The “magical oil” shown herein is eucalyptus, but you could use peppermint or rose (see what I did there?) or whatever other essential oil you like or have…though anything food-related (vanilla, almond, chocolate, etc.) seems ill-advised.

If what you’re trying to do is mask the, um, unsavory aroma of certain human bathroom activities (ahem), this does the trick, naturally and without filling your room with chemical sprays.

However, if you have this sign near your toilet with the bottle of essential oil, you can feel confident that you’ve done your best to cover your tracks, but don’t fool yourself…everyone will know exactly what you did.
